Outline of Final Research Achievements

This research studied a test bed for digital archives of historical documents in Asia. For Vietnamese Chunom documents, we made OCR of more than 40,000 character categories. For wooden tablets excavated from the Heijo palace site, we made an annotation tool including noise reduction and extraction. This annotation tool is availed for archiving an enormous amount of broken pieces of wooden tablets. We are extending the research to other languages in Asia.
